Product details
Overview
PBSS4620PA,115 from Nexperia is an AEC-Q101-qualified NPN low VCE(sat) transistor in a DFN2020-3 (SOT1061) leadless package, rated for 20 V VCEO, 6 A continuous collector current, and 33–46 mΩ RCE(sat) at IC = 6 A / IB = 300 mA. It serves as a high-efficiency load switch in automotive power management and battery-driven motor control circuits.
For engineers reviewing the PBSS4620PA,115 datasheet, PBSS4620PA,115 pinout, PBSS4620PA,115 application, or PBSS4620PA,115 equivalent, key selection criteria include its ultra-low saturation resistance, thermal performance on FR4 and ceramic PCBs, AEC-Q101 qualification, and compatibility with compact 2 mm × 2 mm layouts in space-constrained automotive modules.
Technical Context
This device operates as a medium-power NPN bipolar junction transistor optimized for switching rather than linear amplification. Its design centers on minimizing conduction losses via ultra-low VCE(sat) (200–275 mV) and RCE(sat), enabled by an exposed collector pad for direct thermal and electrical connection to the PCB.
The SOT1061 package integrates a thermally enhanced DFN structure with 1.3 mm pitch and 0.65 mm max height, supporting pulsed ICM up to 7 A and junction temperatures up to 150 °C. It is specified for operation across −55 °C to +150 °C ambient, with derated power dissipation dependent on PCB mounting configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 20 V - Maximum safe collector-emitter voltage with base open; defines maximum blocking capability in load-switch configurations. |
| IC | 6 A - Continuous DC collector current rating; supports high-current switching in battery-powered motors and charging paths. |
| RCE(sat) | 33–46 mΩ - Measured at IC = 6 A / IB = 300 mA; enables <150 mW conduction loss at full load, reducing thermal stress. |
| hFE | 200–330 - DC current gain at IC = 6 A; ensures reliable saturation with modest base drive (e.g., 300 mA), easing MCU GPIO or driver IC interface. |
| Tj(max) | 150 °C - Maximum junction temperature; allows sustained operation in under-hood automotive environments with appropriate PCB thermal design. |
| AEC-Q101 | Qualified - Certified for automotive applications per Stress Test Qualification for Discrete Semiconductors; supports functional safety-aware designs. |
Pinout & Package
Encapsulated in a 3-terminal DFN2020-3 (SOT1061) ultra-thin leadless plastic package (2.0 mm × 2.0 mm × 0.65 mm), featuring an exposed collector pad for thermal and electrical integration with the PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input node; requires ~300 mA drive for full saturation at 6 A collector current; low VBE(sat) (0.97–1.1 V) minimizes base drive power. |
| 2 | Emitter (E) | Reference node for collector current path; connected to system ground or low-side return; forms common-emitter switching topology. |
| 3 | Collector (C) | Main power output terminal; electrically and thermally tied to exposed copper pad on underside; carries full load current and dissipates heat directly into PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RCE(sat) | 33–46 mΩ at IC = 6 A enables <150 mW conduction loss, critical for thermally constrained battery systems. |
| Thermally enhanced DFN | Exposed collector pad reduces Rth(j-a) to 60 K/W on ceramic PCB, enabling higher sustained power without heatsinks. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD testing-supports ASIL-B–compatible subsystems. |
| Compact footprint | 2 mm × 2 mm body occupies ~75% less PCB area than comparable SOT23 or TO-252 devices, freeing layout space in ECUs and BMS modules. |
Applications
| Automotive Load Switch | Battery-Powered Motor Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN low VCE(sat) transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40201MR6T1G | Same 20 V VCEO, 6 A IC, but higher RCE(sat) (45–65 mΩ); SOT-23 package with no exposed pad. | Limited thermal performance on FR4; unsuitable for sustained >3 A loads without significant derating. | Prefer when board space is extremely limited and thermal load is light; avoid for automotive under-hood use. |
| Diodes Incorporated DXT601100Q-7 | 20 V VCEO, 6 A IC, RCE(sat) = 35–50 mΩ; DFN2020-3 package with AEC-Q101 qualification. | Nearly identical thermal and electrical specs; slightly lower hFE (180–300) requires marginally higher base drive. | Drop-in alternative where Nexperia supply is constrained; verify layout compatibility with marking and solder paste stencil. |
Compared with NSS40201MR6T1G, PBSS4620PA,115 delivers superior thermal management and lower conduction loss due to its exposed-pad DFN package and tighter RCE(sat) spec; versus DXT601100Q-7, it offers higher hFE and more consistent VCE(sat) across temperature, simplifying base drive design in automotive ECUs.

FAQ
What is the recommended PCB layout for optimal thermal performance of PBSS4620PA,115?
For best thermal performance, connect the exposed collector pad to a minimum 1 cm² copper pour on the top layer using at least four 0.3 mm diameter thermal vias to an internal or bottom-layer ground plane. Use the reflow footprint specified in Figure 17 (sot1061_fr), with 0.55 mm solder mask opening and 0.4 mm solder paste stencil aperture per pad. Avoid solder mask over the exposed pad.
Can PBSS4620PA,115 be used in high-side switching configurations?
Yes, PBSS4620PA,115 can be used in high-side configurations, but requires level-shifted base drive capable of delivering ≥1.1 V above the collector rail to ensure saturation. Due to its NPN structure, it is more commonly deployed as a low-side switch; for high-side applications, consider pairing with a dedicated high-side driver IC or using a PNP complement like PBSS5620PA.
What is the maximum allowable base current for continuous operation?
The absolute maximum base current is 600 mA per datasheet limiting values. For continuous 6 A collector operation, the recommended base current is 300 mA (IC/IB = 20), which ensures deep saturation while maintaining reliability. Exceeding 300 mA does not significantly reduce VCE(sat) but increases base drive power and thermal load on the driving circuit.
How does PBSS4620PA,115 perform under transient thermal conditions?
Under pulsed conditions (tp ≤ 300 µs, duty cycle ≤ 0.02), PBSS4620PA,115 maintains stable VCE(sat) and RCE(sat) due to low transient thermal impedance-e.g., Zth(j-a) ≈ 125 K/W at 1 ms on FR4 with 1 cm² collector pad. This enables reliable 7 A peak current handling without junction overheating, provided average power remains within derated Ptot limits.
